Does it seem like your lunchbreak goes too quickly? It's time to reverse the effect with the Lunchtime Clock by Instructables user randofo. This clock slows down during the lunch hour so that you can relax a little:

Thanks to great in advances in clock technology, I present to you a clock that speeds up 20% every day at 11:00 and slows down 20% every day at 11:48, giving you an extra twelve minutes of lunch to enjoy. Twelve minutes may not seem like a lot but, to put it into perspective, this is a full additional hour of lunchtime gained every week.
